Resumen (es_ES)

Se muestra la implementación de algoritmos de flujo óptico y
extracción de características para el reconocimiento y detección de objetos en tiempo real de una secuencia de imágenes. Se implementaron algoritmos de flujo óptico y de detección de características SIFT, SURF y un estudio sobre la influencia de los cambios de iluminación en el ambiente de la escena analizando el
funcionamiento y desempeño. Durante los cambios de iluminación se encontró que los puntos de interés entre dos imágenes consecutivas se reducen debido a que los algoritmos de detección no encuentran patrones similares y todos los niveles de intensidad son diferentes. Los resultados experimentales muestran que el algoritmo propuesto es funcional en escenas donde la luminosidad es constante y no es inferior a 1 Lux, se entrega una herramienta útil para sistemas de vigilancia y robótica móvil.

Resumen (en_US)

This paper shows the implementation the optical flow algorithms
and feature extraction for recognition and objects detection in real time with a sequence of images. The algorithms used are optical flow, SIFT and SURF.
It was conducted a study on the influence of changes in the ambient lighting of the scene examine the functioning and performance of each proposed algorithms. During illumination changes was found that the points of interest between two consecutive images is reduced because detection algorithms are not similar patterns and levels of intensity are different. The experimental results showed that the proposed algorithm is functional in scenes where the brightness is constant and not less than 1 Lux, it provides a useful tool for surveillance systems and mobil robot.
